Tips:
Obscure comes from the Latin root scurus, "covered." Something obscure is often hidden or hard to detect. Generally, anything that is unclear, hard to find or figure out, or not widely known can be described as obscure. The verb obscure means "to darken something or make it less distinct or understandable."

Usage Examples:

This beautiful sculpture was created by an obscure artist from a small town, but I'm sure he'll be famous some day. (unknown) adjective
